It leads to some interesting possibilities. I have to wonder how habitable a moon would be if it were tidally locked with its planet like ours is. A night that’s a couple of weeks long would get mighty cold I would think.
Also interesting is the possible day night pattern. You have the night that results from the rotation of the moon plus a “total night” that would result from passing behind the planet in the darkness.
We know from our own solar system that moons are pretty varied.
